WATCHMANS ELECTRIC TIME-RECORDER.

SPECIFICATION forming part of Letters Patent No. 482,251, datedSeptember 6, 1892.

Application filed March 2, 1892.

To all whom it may concern:

Be it known that I, EMANUEL R. IIEYSER, of Leon, Mexico, have invented anew and Improved VVatchmans Time-Check, of which the following is aspecification, reference being had to the annexed drawings, forming apart thereof, in which Figure 1 is a side sectional elevation of myimproved apparatus, taken on line x 00 in Fig. 2. Fig. 2 is a horizontalsection taken on line y y in Fig. 1. Fig. 3 is an enlarged sideelevation of the paper-moving roll. Fig. 4 is an enlarged verticaltransverse section taken on line 1 y in Fig. 2, and Fig. 5 is aperspective view of the ink-ribbon holder.

Similar letters of reference indicate corresponding parts in all theviews.

The object of my invention is to construct asimple and effectivewatchmans time-check which will indicate the presence or absence of thewatchman at a given point at certain intervals of time.

My invention consists in a time movement provided with electriccircuit-closing devices for closing the electric circuit at statedintervals, a ratchet-wheel carrying figures representing the hours anddots for the half-hours, electro-magnetic apparatus placed in thecircuit of the clock circuit-closer and provided with an armature-levercarrying a pawl for actuating the ratchetwheel,a spring-actuatedprinting-bar for pressing the characters upon the printing-surface,means for intermitting the action of the printing-bar, and mechanism formoving the strip upon which the impressions are made, all as will behereinafter more fully described.

The mechanism for closing the electric circuit of my improved apparatusconsists of a clock A, having a dial a and hands I) 0, constructed andarranged in the usual way, and the electric contact-strips d e, securedto the dial at diametrically-opposite edges and covering a spaceequivalent to five minutes of time by the clock. The said contact-stripscl 6 are insulated from the dial, and being in the path of the end ofthe minute-hand b are each touched once during one revolution of theminute-hand. The contact-strips d e are provided with binding-posts andare both connected with one pole of the battery 13, the other pole ofwhich is connected with the elec- Serial No. 223,496. (No model.)

tro-magnetic check mechanism C, which is connected electrically with themovement of the clock A.

In standard f, secured to the bottom of the casing D, is journaled theshaft h of the ratchet-wheel E, said ratchet-wheel having 011 itsperiphery twenty-four teeth, and upon one side of said ratchet-wheel,opposite alternate teeth, are formed characters corresponding with thoseon the clock-dial and representing the hours of the day. Oppositeintermediate teeth are located projections corresponding with thehalf-hours.

In one end of the casing D is fixed a magnet F, which is connectedelectrically with the battery 13 and with the movement of the clock A.To the bottom of the casing D is attached a plate 1', to which ispivoted the armature-leverj, carrying an armature 7a, which is withinthe field of the magnet F. The armature-leverj is prolonged above thearmature 7c, and to the extremity thereof is pivoted a hooked pawl Z,which engages the ratchetwheel E. The armature-lever j also carries anangled arm m, the end of Much is enlarged, forming a platen ofsufficient size to cover the characters formed on the ratchet-Wheel. Thearm m is rigid in a vertical direction, but is capable of swinginglaterally when pressed by the printing -bar G. The said printing-bar Gmoves in guides in the casing D and one end thereof projects through thefront of the casing and is furnished with a knob 91, by which it may bedrawn outwardly preparatory to releasing it for the purpose of printing.On the bar G is placed a collar 0, between which and the front of thecasing D is placed a spiral spring p. A forked arm II, secured to thestandard f, carries an ink-ribbon q in front of the ratchet-wheel E andopposite the path of the characters, carried by the wheel. In front ofthe ink-ribbon is carried a strip 7' of paper, which is taken from areel I, located at one end of the casingD and wound upon a reel J at theopposite end of the casing. The shaft of the reel J is provided with aspur-wheel s, which is engaged by a similar spur-wheel t on a shaft to,journaled in the arm 1), which supports the upper end of the reel-shaft.The shaft to also carries a ratchet-wheel w, which is engaged by aspring-pressed pawl a, pivoted to one end of the lever b, the other endof the said lever being connected with the printing-bar G by a link 0.The spring-pressed detentpaWl a engages the ratchet-wheel w and preventsretrograde movement. The armaturelever j is held normally against thelimitscrew 6 by the spring f, attached to the bottom of the casing andpressing against the said lever.

The operation of my improved apparatus is as follows: \Vhen theminute-hand bof the clock A makes a contact with the contact strip (1 ore, the circuit of the battery B is closed and the magnet F is energized,drawing forward the armature 7c, and with it the armature-leverj. Thisoperation moves forward the ratcl1et\vheel E one notch, bringing a dotor a character opposite the printing-bar G, at the same time bringingthe end of the arm 1% between the said printing-bar and the paper strip0'. If under these circumstances the watch man on duty withdraws andreleases the bar G bygrasping the knob 11 and releasing it, the impactof the bar upon the enlarged endof the arm m will press the paper strip7' against the ink-ribbon g, which in turn is pressed against theprojecting dot or character on the wheel E, thus forming on the paper animpression of the said dot or character. If the watchman does not pullthebar G during the time that the circuit of the battery B is closed onthe magnet F by the clock A, the pulling of the rod will not produce animpression on the paper, as the armature-leverj is thrown back when thecircuit is broken, thereby carrying the arm m out of the path of the barG, thus preventing the bar G from exerting pressure on the wheel E andintermediate devices. In consequence of this no record can be made, andthe paper strip will show a neglect of duty on the part of the watchman.Whenever the bar G is drawn out preparatory to making an impression, thepawl a, through the medium of the link 0 and lever b, is made to engagethe ratchetwheel to and turn it, thereby turning the reel J and drawingforward the paper-strip so as to present a new surface for printing. Asthe electromagnetic mechanism which turns the ratchet-wheel E isentirely independent of the printing mechanism, the said ratchetwheel isturned one notch every half-hour, so that when the impressions on thepaper do not show the hour and half-hour marks in regular succession theinterval of the absence of the watchman from the instrument can bereadily determined.

It is obvious that the printing-wheel E may be operated independently ofthe time-circuitclosing device, as under some conditions a push-buttonmay be substituted for the time circuit closer. It is also obvious thatthe time-circuit closer may be usefully employed in other Ways.Therefore I do not limit or confine myself to the exact combination orarrangement herein set forth.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In a watehmans time-check, the combination, with aclock and an electrical device connected therewith, of a printing-wheeloperated by the electrical device and having its characters on one side,an ink-ribbon in front of the printing-wheel, a strip of paper in frontof the ink-ribbon, a printing-bar to be operated by the watchman, and aplaten moved in and out of the path of the printing-bar by theelectrical device, substantially as described.

2. In a watehmans time-check, the combination, with a clock and anelectrical device connected therewith, of a printing-wheel operated bythe electrical device and having its characters on one side, anink-ribbon in front of the printing-wheel, paper-reels mounted to allowthe paper to pass in front of the in kribbon, a printing-bar to beoperated by the watchman, a platen moved in and out. of the path of theprinting-bar by the electrical device, and means for rotating one of thepaperreels from the printing-bar, substantially as described.

In a watehmans time-check, the combination, with a printing-wheel, aninkingribbon, and paperreels, of a springpressed printing-bar to beoperated by the watchman, a platen moved in and out of the path of theprinting-bar, and mechanism between the printing-bar and one of thepaper-reels for operating the said reel from the printing-bar,substantially as described.

at. In a watchmans time-check, the combination of the ratchet-wheel E,carrying characters representing the hours of the day, theeleetro-magnetic wheel-operating device consisting of the electro-magnetF, the springpressed armature-lever j, provided with the arm m and pawlZ, adapted to engage the ratchet-wheel, the spring-pressed printingbarG, arranged to press upon the arm on, and the electric generator andcircuit-closer, substantially as specified.

5. The combination, with the time-printing mechanism, of the reel I,carrying the paper strip 0', the reel J for receiving the paper strip,the ratchet-wheel w, the lever Z), the springpressed pawl a, the link c,and the printingbar G, substantially as specified.
